3. Relatively complex molecules can be synthesized using relatively few stereospecific reactions. Using the starting materials given in the box, along with any other common reagents, propose a synthesis for molecule A. Pay special attention to relative stereochemistry (enantiomeric mixtures are acceptable). Include both a retrosynthetic analysis and a detailed forward synthetic scheme complete with reagents. You really do know all the steps for this! Work backwards using retrosynthesis to identify the needed steps
